L/0yd B. Smith United States 'I rlis-in'v'entioii-relates to a sprinklerarid mbr'epar'tig larly'to a wav'e type-sprinkler adapted 'for'sprinkling lawns andtli'e like? p u 7 An object of my' invention isto'providea sprinkler ot the character designated in which the'w'ate'r isdistributed evenlyover theentire sprinkler pattern, whereby there is no'excess'of-wa'ter adjacent theouter edge or the pattern. p t s Anotherobject-of my invention is' to provide a sprinkl'r" of'th'e" characterdesignated which shall embody'a vfaite'r" motor having a vane-mountedfor pivotal n'iove ment and a sprinkler c oii'duit connected nonrota'tably to the va'ne, m eaier with pressure release means for by:passing watertothspriiikler conduit, whereby the by passed water doesnofact'upon the vane fiJrther in creasethe speedof; oscillation" smegma;providing awt'ater niotorwhicli oscillates ata predetermined speed.

A furthe'r object of 'my invention" is to prot' ide' a wa'ye type watersprinkler'of thech'araqter designated which the" angular pivotalmovement ofthe" sprinkler is adjust able whereby-the sprinklerpatternmay be'varied,

A still further object of my'invention-is 'to' provide a sprinkler ofthe character designated which shall be simple of construction,economical of manufactureand one which is trouble'free in" operation andrequires a minininm of maintenance.

Heretofore' in theart to which my invention-relates; various types ofwave type sprinklers have been proposed. However, such sprinkle'rs withwhich I am far'riilar are unsatisfactory due to the fact that the Watermotor is actuated by Water which does not pass through the sprinklerconduit. Thatis, the Water which actuates the water motor is dischargedfrom thewater motor without enter ing the sprinkling conduit. Also, wavetype sprinklers heretofore employed} have required a complicated assembly of parts which requires considerable maintenance to maintain thesame in trouble free operation. Furthermore, no effectiye means has beenprovided to regulate'thespeed at which the sprinkler conduit oscillates.

Briefly; my'impr'oved' sprinkler comprises a water meter havingavane/mounted for pivotal movement in a casing and including a'waterinletand a Water outlet. A sprinkler conduit is connected to th e vane of themotor and the'water outlet thereof and is'adapted 'to'oscillatetherewith. V To regulate the speed at which the vane and the sprinklerconduit oscillate, I provide pressure release means'to bypass water tothe sprinkler conduit when'the water pressure-exceeds a predeterminedamount;

Telescoping within the-conduit 19 atubular member disposed. to engagethe partition 29, as shown in Fig. 5,

34 which is interposed between a spring abutment 36 carried by the valvemember 32 and the adjacent side of the partition 29. It will thus beseen that as the pressure within the tubular member 28 increases to apoint that it overcomes the force exerted by the spring 34, thedisc-like member 33 is moved outwardly from the partition member 29 toallow water to flow through the opening 31.

Oppositely disposed openings 37 and 38 are provided in the tubularmember 28 at opposite sides of the partition 29 whereby they are inalignment with the elongated openings 21 and 22 in the conduit 19. Itwill thus be seen that with the tubular member 28 in the position shownin Fig. 3, the water entering the tubular member passes through theopenings 38, 22 and 18 into the casing 12 adjacent one side of the vane26. .Any water on the opposite side of the vane 26 then flows into thetubular member 28-through the openings 17, 21 and 37 at the oppositeside of the partition 29 whereby the water is discharged through theconduit 19 and sprinkler orifices 24. The tubular member 28 is alsoprovided with oppositely disposed openings 39 and 41 which arepositioned at opposite sides of the partition 29. As shown in Fig. 3,the openings 39 and 41 are spaced angularly from'the openings 37 and 38whereby upon rotation of the tubular member 28 in a counter-clockwisedirection from the position shown in Fig. 3, the openings 39' and 41move in 'to'register with the openings 21 and 22 in the conduit 19. Inthis latter position, the water entering the inlet end of thetubular'member 28 passes through the openings 39, 21 and 17 into'theadjacent side of thecasing 12.

alternately with the openings 37 and 39 and 38 and 41,

respectively, whereby the water is introduced alternately at oppositesides of vane 26. In view of the fact that the openings 37 and 41 movein to register with the openings 17"2 1 a.nd.1822 as the vane 26 isoscillated, the water 'is exhausted alternately through the openings 37and 41 into the tubular member 28 and the conduit 19 where his conveyedto the sprinkling orifices 24. Mounted adjacent each side of the tubularmember 16 within the casing 13 are outwardly extendingmembers 42 and 43.Telescoping over the inlet end of the member 7 16 is a collar 44 havingan outwardly projecting arm 46 which is in position to be engaged bythe-projections 42 and 43 as the vane 26 oscillates the tubular member16;

Secured to the outerend of, the tubular member 28 and adapted forpivotal movement therewith is an'outwardly projecting arm 47. Pivotalmovement of the arm 47 is limited by adjustable stop members 48 and '49which are carried by an actuating member 51. Connecting the outer endsof the arms 46 and 47 is a spring member 52 which urgesv the arms 46 and47 in opposite directions when the pivotal connection between the arm 46and the spring 52 passes dead-center of a line extending radiallyprojection 43 engages the arm 46 and moves the same" toward the left orin a clockwise direction. As the pivotal nection between the arm 47 andthe spring 52, the spring 52 causes the arm 47 to move quickly towardthe right and into engagement with the stop member 49. In the latterposition, the 'water is introduced into the casing 12 through theopening 39 and discharged therefrom through the opening 41.

The actuating member 51 is provided with a control knob 53. Interposedbetween the control knob 53 and the housing 10, as shown in Fig. 1, is acompression spring 54 which urges the knob 53 outwardly of thehousing10. As shown in Fig. 4, the actuating member 51 carries a series ofnotches 56 which are in position to engage a stop member 57 to hold theactuating member 51 in selected position. To operate the actuatingmember 51, the knob 53 is pushed inwardly against the compression ofspring 54 whereupon the notches move out of engagement with the stop 57to permit free rotation of the actuating member 51. Upon moving theactuating member to the desired position, the'knob53 is released toreturn the actuating member in the desired locked position. With theactuating member 51 extending in a horizontal plane; as shown in Figs. 1and 4, the sprinkling conduit 19 oscillates equal distances at each sideot a vertical plane passing through the center of the conduit 19.Preferably, in this position, the conduit oscillates 45 at each side ofthe vertical plane passing through the axial'icenter line of theconduit19. To cause the conduit 19 to rotate a further angular distancetoward either side, the control'knob 53' is actuated to move the stops48 and 49 in the proper direction. That is, if it is desired tooscillate the conduit 19 further toward the counter-clockwise direction,the control, knob is pushed inwardly and turned in a counter-clockwisedirection to reset the actuating member 51. On the otherhand, if it isdesired to oscillate the conduit 19 further in a clock- I wisedirection, the control knob 53 is pushed inwardly and rotated in" aclockwise direction to reset the actuating member 51. The stops 48 and49 are thus positioned at selected angular positions whereby the angularmovement of the sprinkling conduit 19 may be varied.

I From the foregoing description, the operation of my improved sprinklershown in Figs. 1-6 will be readily understood; The hose connection 1'4is connected to a water supply hose and the knob 53 is set at thedesired position to determine the angle of oscillation of the sprinklingconduit 19. With the tubular member 28 in the position shown in Fig. 3,wateris'introduced through the connection 14 into-the casing 13 andthence through the inlet of the tubular member 28. The water then passesthrough the openings 38, 22 and 18 into the casing 12 adjacentthe rightside, of the vane 26, as viewed in Fig.3, The water at the other sideofthe vane 26 is then exhausted. through the openings v17, 21" and 37 into'jection1'43 engages the arm '46"and,frotates.the same in a a clockwisedirection. As the pivotal connection between the arm 46 and the spring52 passes dead-center ofaline extending radially from the axial Icenterof'the tubular member '28 through the connection of the arm 47 to thespring, 52, the spring 52 -urges the arm 47 quickly in acounterclockwise direction 'to-position the openings 39 connectionbetween the arm 46 and the spring52 passes dead-center of a lineextending radially from the axial center ofthe tubular member 28 and thepivotal conand 41 in register with the openings 17 -21 and 18--22,respectively. In the latter position, the water enters the inlet end'ofthe tubular member 28- and passes through the opening 39 into the casing12adjacent the left-hand side of the vane 26, as viewed in Fig. 3, thuscausing the vane 26 to be oscillated in a' counter-clockwise direction.Water at the oppositeside of'theva'ne 26 is then exhausted through theopenings 18,- 22 and 41 to the tubular member 28 and thence outwardlythrough the conduit 19 to the sprinkler orifices 24. i

If it is desired tovary the angular pattern made by the sprinklerconduit 19, the knob 53 is compressed inward meshes 3 and moved. in thedesired direction and thenre'l'eased to setthe stops 48 and'49 in thecorrect angular positions relative to the arm 47.

Should the pressure of the water'in the tubular member exceed apredetermined amount, which is"determinedby the spring 34, the'valve'32is unseated wh'ereby water bypasses-through the opening 31"and' thenceto the sprin kler conduit 19. By providing the pressure relief valve 32,the vane 26 oscillates'at'acontrolled speed;

Referring now to Figs: 7; 8* and9 of-thvdrawings', I show anotherform'ofmy invention'which comprises a housing 19a separated 'by a vertical'wall 11a 'intoa water motor casing'12a and actisinglSiz:Water"is'supplied to the casing 13a by a suitabl"hose"connection?14h.Extendinggthrough the casing"12i1' isa sprinkler conduit 19ahavingaplurality of" sprinkler orifices 2421 therein; The sprinkler conduit19a is'secured "to a suitable bearing sleeve member'58, as shown in Fig.8. Secured "to the sprinkler-conduit 19a andadapted forpivotal movementtherewith is a water motor vane 26a:

The wall l lais provided with openings 59 and 61 at opposite sides ofthe vane 26a, as shown in Fig. 7. The casing 13a is covered by asuitable outer wall or cover plate 62, as shown. Also, the casing 13a isof'a shape shown in Fig. 7 and is provided with an opening 63 whichencircles the sprinkler conduit 19a and the openings 59 and 61, asshown. The opening 63 is provided with a lower portion in position tocommunicate with the hose connection 14a whereby water is introducedinto the casing13a.

Mounted for pivotal movement between the walls 62 and lla of the casingran on a suitable pivot pin 64 is a valve plate member 66. As shown inFig. 7, the'casing 13a is 'provided'with inwardly extending projections67 and 68-adjacent opposite sides of the'valve plate member 66 adjacentthe opening 59. In like manner, the casing 13ir'is provided withinwardly extending'projections 69 and-'71 at opposite sides of the valveplate member 66 adjacent the opening 61. With the valve plate 66 in theposition shown in solid lines in Fig. 7, opposite ends thereof engagethe projections 67 and 71 whereby water enteringthe opening 63 passesthrough the opening 59 intothe adjacent side of th'e'casing 12a; As thewater forces'th'e vane 26a in a counter-clockwise direction, as viewedin Fig.- 7, the water 'at the opposite side of the vane 26a flows outthrough the opening 61-into'the cas ing'--13a above the valve plate'66and thence'through the sprinkler conduit 19a to the sprinkling orifices24a. On the other hand, when the valve plate member 66 is moved to-ithedotted line position, the water entering the casing 136 through the hoseconnection 14a enters the opening 61," thus forcing the valve plate 26ain a clockwise direction, as viewed in Fig. 7. Any water at the oppositeside of the vane 26a is then exhausted through the opening 59' above theplate 66 to the sprinkler conduit 19a and then to the sprinklingorifices 24a.

The valve plate 66 is actuated by-means now to be described. Secured tothe valve plate 66 and projecting upwardly therefrom are a pair of arms65 which are pivotally' connected at their upper ends'to parallel linkmembers 68. The upper ends of the link members 68 are connected by a pin75; Lateral movement of the links 68 is limited by a pair of stops 70and 72 mounted on Wall 11a at opposite sides of the Connecting the pins75 and 64 is a-spring 73.51, as-shownin-Figt 8.

Frictionally connected to theinlet end of the sprinkler conduit 19awithin the casing 13a is an annular member 73which has a cut-out portion74 therein for receiving the upper end of the link- 68 and the pin 75.Mounted on thesprinkler conduit 19a adjacent the annular mem ber 73 .isa second annular member 76 which has a cut-out portion177t ln view ofthe fact that the annular member 73 is frictionally connected to theconduit 19a, it may be trotatedrelative to the annular member 76,thereby 6 varyingthe size o f the gap for 'receivingthe"pin" 75 andtheupper ends of the-link'sfis. 7

From the foregoing description, the operation of my sprinkler shown inFigs. 7, 8 and 9 will be readilyunder stood. Water is introduced throughthe hose connection 14a whereit'passes'intoth'e casing-13 and throughthe opening 59 beneath the valve plate"6'6 into the casing 12a; Asthewater passes'into the'ca's'ing 12a adjacent the opening '59-; the vane26a is pivoted a' counterclockwise direction; asviewed' in Fig; 7.Counter-clockwise movement of theVaneZG'acaUss corresponding movement ofthe'sprinkler 'conduit19d" and the annular members" 73 and 76'until'thepin"75 engages the 'member 76. Upon engagement of the pin 75 bythe member 76, thelinks 68 arem'ovedab'out their pivotal connection tothe arms 65 until this pivotal connection moves past dead-center ofalin'e "extending through the pins 64 and 75. The'valve plate member 66is then moved quickly, by the spring 73a, to 'the'dotted linep'ositionshown in Fig. 7. In the dottedlin'e position, the water entering thehose connection'14d'pass'e's throughthe opening 61 into theadjacent'side of'thefcasing 12a Any water at the opposite side of casing12a is exhausted through the opening 59 to the conduit 19a and thenceto' the sprinkling orifices 24a.

To vary the angular movement of the sprinkling conduit 19a, theannular'member 73 is rotated relative to the annularmember'"76,' wherebythe gap between the members 73 and76' can'be varied. That is, by movingthe member 73 in a"counter ciockwise"direction, the'gap for receiving.the pin 75 'is increased whereas rotation of the member 73"in aclockwisedirection decreases the gap, thus reducing the distance that the'sprinklin'gconduit 1% moves. I

Theva'lv'e plate member 66als6 servesas aprssure release valve to bypasswater from the casing 13a to'the conduit 19a when an eXc'ess pressureexists" within the casing 13a. That is; when there is an excess'waterpresure within the casing 13a, the valve plate"66 will be forced awayfrom the points'68 and 71, as the'case may be, whereby'a'port'ion of thefiuid'passe's' directly to the sprinkler'conduit 19a. .The tensionspring '73:; serves as a means to actuate the'valve plate member 66instantaneously whereby there'is' no retarded movement of the sprinklerconduit 19aat"each"end' of its travel, thus assuringp'roper'distribution 'of the water.

Referring now to'Figs; l0 and ll of the drawingsil show anothermodification of my sprinkler. The sprinler comprises a housing10b'se'parated by'a partition wall llb into a water motor casing 12b anda casing 13b for receiving water from a hose connection 14b; Extend ingthrough the water motor casing 121: isa sprinkler conduit 19!) havinga'plurality" of sprinkler orificesldb therein for dispensingfwat'er.Secured to'and mounted for pivotal movement with the sprinkler conduit1% is a'w'ater motor vane26b. Water is introduced into the casing 12bthrough a'pairof angularly spaced open ings 78 and 79. As shown in Fig.11, the openings 78 and 79 are positioned at opposite sides of the watermotor vane 26b. Communicating with and adapted for pivotal movementrelative to'the'inletend'of the sprinkler conduit 19b is one end of anL-shaped conduit 81. The other end of the conduit 81 is adapted to'bemoved selectively into engagement with the openings 73 and 79 wherebywater is exhausted through theconduit 81 to 'a' sprinkler conduit 19!).

Mounted for'pivotal movement adjacnt the inlet end of the sprinlerconduit 1% within the casing 13b is one end of an outwardly extendingarm82. The other end of the arm 82 extends inwardly as at83 toward thepartition wall 111), as shown in Fig. 10. Pivotallyconnec'ted adjacentthe outer' end of the conduit 81 is one end'of "a spring member 84. Theother end of spring 84iscon nected to the outer end'of"'arm"82. Thespring'="8s"'is thus adapted to urge thearni "82 and conduit 81 inopinto register with the opening 79.

7 posite directions when the pivotal connection between the spring 84and the arm 82 passes dead-center of a line .extending radially throughthe axial center of the conduit 19b'an'd the pivotal connection betweenthe spring 84 and the conduit 81. Suitable stop members 86 and 87 areprovided at opposite sides of the arm 82 to limit angular movementthereof. Also, stop members 85 and 85a are provided at opposite sides ofthe conduit 81 to limit rotation thereof. Secured to the sprinklerconduit19b adjacent the arm 82 is an actuating member 88 having a recess89 therein defining shoulders 91 and 92 which are disposed to engage theinwardly extending portion 83 of the arm 82 upon rotation of thesprinkler conduit 19b.

Communicating with'the inlet to the casing 13b adjacent the hoseconnection 14a is one end of a conduit 93. The other end of the conduit93 is connected to a pressure relief valve 94 which may be in the formof a valve member 96 which is urged toward seated position by means of aspring 97. Communicating with the valve 94 is one end of a flexibleconduit 98. The other end of the flexabie conduit 98 is in communicationwith the sprinkler conduit 19b whereby the sprinkler conduit is theL-shaped conduit 81 to the inlet end of the sprinkler conduit 19bwhereupon the water passesrout through the 1 spray orifices 24b. As the'waterenters the opening 79,

the sprinkler conduit 1% rotates in a counterclockwise directionjandcarries with it the actuating member 88. The shoulder 92 thus engagesthe inwardly extending portion 83 of the arm 82 and rotates the same ina counter-clockwise direction until the, pivotal connection of the arm82 and the spring 84 passes dead-center of of a line extending radiallyfrom the axial center of the conduit 1915 through the pivotal connectionof the spring 84 to the L-shaped conduit 81. The conduit 81 is thenmoved quickly toward the left, as viewedv in Fig. 11, In this'latterposition, water is introduced into the casing 1211 through the opening78 and'water at the opposite side of the vane 26 is exhausted throughopening 79 and'L-shaped conduit 81 to the sprinkler conduit 1% and thesprinkler orifices 24b. It will thus be'seen that as the water isintroduced Referring now to Figs. 15 and 16, I show a still furthermodified form of my invention which comprises a hous- =ing 10d separatedby a partition wall 11d into a water motor casing 12d and a secondcasing 13d. Water is introduced into the casing 13d by a suitable hoseconnection 14d. Mounted in the casing 1 2d for pivotal movement with asprinkler conduit 19d is a water motor vane Water is introducedalternately at opposite sides of the vane 26dthrough openings 104 and106. Communicating with and adapted for pivotal movement relative to theinletend of the sprinkler conduit 19d is one end of an L-shaped conduit107. The other end of the L-shaped conduit 107 is adapted to registeralternately with the openings 104 and 106 for exhausting water from theeasing 12d at opposite sides of the vane 26d. Secured to the sprinklerconduit 19d adjacent the L-shaped conduit 107 is one end of an outwardlyextending arm 108. Mounted for pivotal movement on the sprinkler conduit19d adjacent the arm 108 is an actuating member 109 having a recessportion 111 defining shoulders 113 and 114 which are in position toengage an inwardly extending pin 116 carried by the L shaped conduit107, as shown in Fig. 15. Extending outwardly of theactuating member 109are stop members 117 and 118 which are adapted to be engaged by oppositesides of the arm 108 as the arm is rotated in opposite directions; Thelower end of the actuating member 109 has a cam surface 119 which isengagedby a cam follower 121. The cam fol-. lower is urged intoengagement with'the cam surface 119 by awcom pression spring 122.suitable stops 120 and 120d areprovided at'opposite sides of the L-shaped conduit 107 to limit rotation thereof.

' Inoperation, water is introduced into the casing 13d through the; hoseconnection 14d where it flows into the exposed opening 104 or 106, asthe case may be. With the apparatus in the position shown in Fig. '16,water is introduced through the opening 104whereby the vane 26d isrotated in a counter-clockwise direction. As the alternately at oppositesides of the vane 26b, the vane and the sprinkler conduit 19b carriedthereby is oscillated.

In Figs. 13 and 14, I show another form of my invention in which thepressure relief means is mounted in the vane 26;: of a water motor. Theexhaust of the water motor is operatively connected to a sprinklerconduit 19c whereby the sprinkler conduit is oscillatedin the mannerdescribed above. The water motor is housed within a suitable housing 100which is divided into'a water motor casing 120 and a second casing 13::by a partition wall 11c. Water' is introduced into the casing 13!: by asuit- V arrows and 103, respectively.

vane rotates in a counter-clockwise direction, the arm 108 engages'pin118 and rotates the actuating member 109- until the apex of the camsurface 119 passes the cam follower 121. The shoulder 114 of theactuating member 109 then engages the pin 116 carried by the L- shapedconduit 107 whereupon the conduit 107 is moved quickly into engagementwith the opening 104. .The vane 26d is then moved in a clockwisedirection until the arm 108 engages the pin 117 and moves the actuatingmember 109 whereby the cam follower 121 passes the apex of the camsurface 119-whereupon the shoulder 11'3 engages the pin 116 and returnsthe L-shaped conduit 107 into register with the opening 106. As Water is'introduced selectively into the openings 104 and 106 it is exhausted'at the'other side of the vane 26d through openings 106 and 104,respectively; That is, the water at the exhaust sprinkler conduit withthe exhaust side of the water motor, in combination'with pressure reliefmeans for bypassing water into the sprinkler conduit when an excesswater pressure is reached, the apparatus operates continuously at acontrolled rate. Also, by providing means for adjusting the angulartravel of the sprinkler conduit, the sprinkler pattern may be easily andquickly varied. Furthermore, my improved sprinkler apparatuscomprises aminimum of parts and a of maintenance to keepthe same in efficientoperating condition. a a T While I have shown my invention in severalforms, it
